OVERVIEW
The WSX Family of wall switch occupancy sensors provides simple and cost effective solutions
for commercial and residential lighting control applications. All WSX Family sensors have a
stylish low profile appearance, soft-click buttons, and provide small motion detection up to 20 ft
(6.10 m), making them perfect for private offices, private rest rooms, closets, copy rooms, or any
other small enclosed space. Additionally, all WSX Family sensors have a patent-pending wiring
method that enables them to function either with or without a neutral connection. WSX units
come pre-configured for wiring without a neutral, however if connection to neutral is required by
code, contractors can convert the unit in seconds.
WSX Family
FEATURES
• Compatible w/LEDs, electronic & magnetic ballasts, CFLs, & incandescents
• 100% passive detection, no potential for interference with other building systems
• Small motion detection to 20 ft
• Push-button programmable without removing cover plate - adjustable time delays &
operating modes
• Dual technology (PDT) utilizes PIR/Microphonics™ detection (patented)
• Self-grounding mounting strap
• Device accomodates powering over ground or neutral connection (patent pending)
• Ultra low current leakage (<0.5 mA) when connected via ground
• Fully meets NEC 2011 Section 404.2C neutral requirements - no current leakage to ground
when connected to neutral
•Line power and load wires are interchangeable - impossible to wire backwards (patented)
•Integrated Photocell (disabled by default) prevents light from turning on if sufficient
daylight is present - not available in Nightlight versions

COVERAGE PATTERNS
• Small motion (e.g., hand movements) detection up to 20 ft (6.10 m), ~625 ft2
• Large motion (e.g., walking) detection greater than 36 ft (10.97 m), ~2025 ft2
• Wall-to-Wall coverage
• Passive Dual Technology (Microphonics) provides
overlapping detection of human activity over the
complete PIR coverage area. Advanced filtering is
utilized to prevent non-occupant noises from
keeping the lights on.
